Fexofenadine hydrochloride 120 mg + Montelukast 10 mg
Allergic rhinitis (seasonal/perennial) with symptoms such as sneezing, runny/blocked nose, itchy/watery eyes; allergy symptoms where leukotriene-mediated congestion is prominent.
Fexofenadine is a second-generation H1 antihistamine that blocks histamine action to relieve sneezing, itching and watery eyes. Montelukast is a leukotriene receptor antagonist that blocks leukotriene D4, helping reduce nasal congestion and allergy-related inflammation.
Tablet for oral use. Take as prescribed, usually once daily, with or without food; swallow whole with water. Avoid taking with fruit juices (apple/orange/grapefruit) close to the dose as they may reduce fexofenadine absorption.
